There are opener and palatine teeth. The maxillary bone is not hidden under the preorbital. 2 dorsal fins separated by a small gap. The lateral line bends slightly towards the caudal stem. The abdominal inter fin fin is small and bifurcated. The body is covered with small scales. The number of branchial stamens in the first branchial arch is 1–4. The vertebrae are 54-56. In the first dorsal fin 16-19 spiny rays, in the second dorsal fin 21-25 and in the anal fin 25-29 soft rays. Behind the second dorsal and anal fins lies a row of 6–9 and 7–9 smaller fins, helping to avoid the formation of whirlpools during rapid movement. The pectoral fins are formed by 20-23 rays.
